Nov. 24, 1953 e. ODLAS MEMORANDUM PLATE Filed Feb. 21, 1952 INVENTOR .GEORG -ODLAS ATTORNEY Patented Nov. 24, 1953 MEMORANDUM PLATE Georg Odlas, Vienna, Austria Application February 21, 1952, Serial No. 272,877 Claims priority, application Austria April 21, 1951 1 Claim.

The invention relates to a memorandum plate which is used to prevent that of a number of articles, e. g., of foodstuffs, household articles, tools, and the like, to be procured, some may be forgotten. The memorandum plate may be used for other purposes too to assist the memory and is intended. primarily for housewives, innkeepers, tradespeople, craftsmen, etc., to aid them in purchasing.

Memorandum plates are known in which a circular disk has an annular groove of T-cross-section, from which short grooves extend outwardly. At the end of said short grooves, inscriptions are provided as references to the articles to be remembered. The annular groove has fitted therein slidable bolts, which .may be introduced into the short groove where the article to be procured is referred to. This type has the drawback that after prolonged use the bolts are a loose fit in the guide grooves and may come out of the short grooves by themselves when the disk is inclined.

Another known type consists of an annular disk having at the inner and outer rim notches over which radial rubber bands are stretched. The ring is divided by radial lines into fields carrying, e. g., the descriptions of articles most conventional in a household. The articles to be procured at a time are marked by hanging a rubber ring into a notch belonging to the respective field. This device has the drawback that its operation is complicated and that it i subject to heavy wear.

In accordance with the present invention a memorandum plate of circular, rectangular, or another suitable shape is provided, which has marked on its one flat side adjacent to the rim n the articles to be remembered, and in which at the rim of the plate a hollow beading is provided, which for the guidance of the indicators has transverse slots. This beading accommodates inside an elastic tension member, e. g., a rubber band, to which the indicators are connected.

The indicators consist of stud beads, stud buttons, stud disklets, or the like. They are clamped to the elastic tension member, e. g., to a rubber band, by means of a hook or eye embracing the tension member or are connected thereto in any other suitable manner.

In the drawing two embodiments of memorandum plates embodying the invention are illustrated.

Fig. 1 is a front view of a rectangular memorandum plate which may be used from one side.

Fig. 2 is a cross-sectional view of the same plate.

Fig. 3 is a cross-sectional view of another embodiment of a memorandum plate having article references on both sides.

Fig. 4 shows another embodiment of a memorandum plate, of circular shape.

Fig. 5 is a diagonal sectional view of the plate shown in Fig. 4.

The memorandum plate shown in Fig. 1 consists of the plate I, the rim of which is conformed as a continuous, hollow beading 3, provided with slots 2. Opposite each slot 2 the reference to one of the articles to be remembered, in this embodiment consisting of articles used by blacksmiths, locksmiths, mechanics, etc., is provided, e. g., by printing. The rim beading 3, preferably having the cross section of a circular ring, contains a resilient tension member, e. g., a rubber ring 4, which has connected thereto the stud beads 6 provided as indicators and guided with their carrying studs 5 in the slots 2 of the rim beading. To this end the stud 5 carrying the bead 6 is reversely bent to form a hook embracing the resilient member 4.

In order to utilize also the back of the memorandum plate, and thus to provide for twice the number of articles to be indicated, or for a reduction in the size of the plate, the latter may be constructed as shown in Fig. 3. In this case article references are provided on both sides. In this type, however, it is essential that any indicators (beads) not used at a time are accommodated between the two printed faces of the plate, e. g., in the continuous groove 8 between the two beads. Separate beads 6, 6' are used for each side of the plate, and are guided in the appertaining slots 2, 2 of the two hollow beadings.

The memorandum plate shown in Figs. 1 and 2 is used as follows:

When the device is out of use, all beads 6 are on that side of the device which has no article references. For purchasing, all articles to be procured are indicated by the beads being moved in the slots 2 associated therewith over the rim beading 3 to the reference to the article to be procured (e. g. 6 in Fig. 1). After the thus indicated article has been bought, the respective bead is moved back over the rim beading 3 to that side of the plate which has no references.

In the embodiment shown in Figs. 4 and 5, a circular plate is used, the hollow annular rim beading 3 of which has radial slots 2 and receives the rubber ring 4, which has connected thereto by means of small hooks or the like the stud beads 6 inserted in the slots 2.

The memorandum plate described is inexpenslve in manufacture, handy, and withstands rough handling. It has no parts subjected to wear. For adaptation to specific requirements it may be provided with difierent inscriptions, e. g., for the conventional articles for household use, for the different tradespeople, craftsmen, etc.

I claim:

A memorandum devicecomprisinga plate, a hollow cylindrical beading along at least a portion of the edge of said plate, said beading having identify reference indicia on said plate-adjacent" each said slot, an elongated elastic'pintlemember disposed eccentrically within said beading adjacent the plate edge portion, and indicators on studs respectively slidable in said slots and pivotally supported by said pintle member, whereby said indicators are normally urged by said elastic pintle member toward the ends of said slots but may be freely swung around said beading due to the elasticity of said pintle member,
